OPERATIONAL FAULT CODES
The following codes indicate that a fault has been detected during drive operation. The drive will remain operational despite the fault. The drive should be replaced at the earliest possible opportunity.
Operational fault codes are indicated as a series of flashes. The fault light will illuminate for 1 second, then off for 1 second, followed by a 10 second off delay. The number of 1 second flashes between each 10 second delay period are used to indicate the different fault conditions: 5, 7 or 9 flashes.
Table 38. Operational Fault Codes
Code | Condition | Description |
|
|
|
5 Flashes | Power Backup Device Faulty | The power backup circuit has failed. The power backup |
|
| circuit supplies power to the drive for a short period in the |
|
| event of a power failure. The backup power allows the |
|
| firmware to ensure that any active writes are completed. It |
|
| also allows information to be saved so that the drive |
|
| becomes ready promptly (< 30 seconds) when power is |
|
| restored. If this fault code is active and power is |
|
| unexpectedly lost, the drive may require several minutes to |
|
| come ready when the power is restored. If this occurs, only |
|
| the data blocks that were most recently written by the host |
|
| will be lost. If those same data blocks are read when power |
|
| is restored, the prior contents (prior to the lost write) will be |
|
| returned. No data will be permanently lost. When this |
|
| fault code is active the drive will save all information and |
|
| prepare for power loss if a SYNCHRONIZE CACHE (10) |
|
| command (Opcode 0x35) is received via the host SCSI |
|
| interface. Most operating systems (Windows, Solaris, |
|
| Linux, etc.) will issue this command automatically when |
|
| shut down by the user. This will alleviate the potential |
|
| problems associated with this fault condition. |
7 Flashes | NAND Flash Write Protect Error | A write protect error was returned when the unit attempted |
|
| to write to the flash media. The most likely cause is a faulty |
|
| connection or voltage converter. If this error occurs |
|
| continuously then access from the host machine will be |
|
| locked out. |
9 Flashes | NAND Busy Error | The BUSY pin from a NAND flash chip was asserted for too |
|
| long. The most likely cause is a faulty connection. If this |
|
| error occurs continuously then access from the host |
|
| machine will be locked out. |
